Open source Java proponents want to modernize the Java memory model, which has not been formally updated in more than nine years, and focus on concurrency.
A JEP (JDK Enhancement Proposal), number 188, dated this month, offers guidance on shared-memory concurrency efforts that impact Java SE (Standard Edition), JVM support, testing, and tools.
"Specifying shared memory consistency models and developing and maintaining features and components that operate in accord with them are among the most central yet difficult issues in engineering concurrent and parallel platforms," the JEP document states. "Specification limitations, errors, and unintended consequences become apparent over time; new hardware platforms, programming techniques, and software components and tools emerge that escape existing boundaries."
